Application filed January 3, 1925. Serial No. 434.

[ all w be m it may con cern Be it known that I, SIGURD H. IIELLAND, a citizen of the United States, residing at lVhitinsville, in the county of Vorcester, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Roving, Spinning, and like Machines, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to an improvement in the supports of the top-ro1ls of roving, spinning and like machines and has for its principal object the production of cheaply constructed and effective means whereby the arms holding the top-roll journals are inde pendently adjustable and are readily removed or replaced when desirable.

Figure 1 is a plan view of a portion of a spinning frame, showing a section of toprolls with their supporting frame and the ends of the adjacent sections. Figure 2 is an enlarged transverse sectional view of a frame on the line 22 of Figure 1. Figure 3 is an enlarged rear elevation in partial section of a roll stand, showing the normal position of two adjacent cap-bar shafts journalled in their common bearing. Figure 4. is an enlarged. rear view of Figure 1 show- .ing my invention in position to permit the removal of one or more of the top-roll supporting arms.

Like references parts in each figure.

Referring to the drawings :3 represents the framing of the machine on which a plurality of roll stands t are mounted. Each stand is provided with an adjustable slide 5 in the upper part of which bearings for the bottom drawing rolls 6 are provided, their corresponding top-rolls 7 being journalled in sockets formed in the supporting arms 8. The hub 9 of each arm is adjustably mounted on the shaft 10 journalled in bearings 11 located in the rear part of slides 5. The arms are positioned on the shaft according to the length of the toprolls and are fastened thereon by any suitable means, preferably the hub of each arm is split open on its upper side; this construction in combination with the clamping bolt 12 securely fastens the arm to the shaft. The hubs 8 of the end arms 9' of each section abut against the sides of the shaft beardenote corresponding ings thus maintaining the cap bar in its proper working position.

The shafts 10, preferably made of cold rolled steel, rotatively mounted in the bearings 11 on the slide 5 are made of such length as to normally leave a pocket 13 in each bearing between the ends of adjacent shafts. This pocket is of suflicient length to permit the shaft 10, after loosening the holding means of the supporting arms, to be moved longitudinally out of its normal position so as to provide an opening sufficiently wide between the other end of the shaft and the side of the bearing whereby one or more of the supporting arms 8 may be readily removed or replaced.

I claim:

1. In a machine of the character specified, a plurality of top-roll sections, a revolvable, longitudinally slidable shaft for each section, a plurality of arms supporting the toprolls and adjustably mounted on the shaft, means for fastening the arms to the shaft, fixed bearings for the shaft located between the ends of two adjacent sections, means for maintaining each section in a stationary position between the bearings and means for the removal or replacement of a top-roll supporting arm. 1

2. In a machine of the character specified, a plurality of top-roll sections, a revolvable, longitudinally slidable shaft for each section, a plurality of arms supporting the toprolls and adjustably mounted on the shaft, a split hub on each arm, a bolt clamping the hub to the shaft, and fixed bearings for the the shaft located between the ends of two adjacent sections, means for maintaining each section in a stationary position between the bearings, and means for the removal or replacement of a top-roll supporting arm.

3. I11 a machine of the character specified, a plurality of top-roll sections, a revolvable, longitudinally slidable shaft for each section, a plurality of arms supporting the toprolls and adjustably mounted on the shaft, means for fastening the arms to the shaft, fixed bearings for the shaft located between the ends of two adjacent sections, hubs on theend arms of each shaft abutting against the sides of the bearings to maintain the section stationary, and means for the removal or replacement of a top-roll supporting arm.

4. In a machine of the character specified, a pluralityof top-roll sections, a revolvahle, longitudinally slidable shaft for each section, a plurality of arms supporting the toprolls and adjustably fixed to the shaft, fixed bearings for the shaftlocated between the ends of tWo adjacent sections, abutting means on the shaft cooperating with the fixed hearings to maintain the section stationai'y and a pocket in the fixedbearings 10 intotwhich one..end of the shaft may be In testimony whereof, I have signed this 15 specification.
